Giant rodents, anyone? The Capybara , a.k.a el chigüire, carpincho, or capivara, is a large rodent that stands around two feet tall and weighs anywhere from 75-140 lbs. I actually had the opportunity to see one live at the Cape May County Zoo in New Jersey, and thought it was one of the most interesting creatures I've ever seen. I think we need this as a new pet to add to our growing animal farm. Sadly, though, I suspect it would cut down on the number of visitors to our home. Would you visit the home of someone who owned a giant, semi-aquatic rodent that likely smells like dirty river water? I would!
